'To all whom it may concern.-

Be it known that I, ELISE GoL'rs'rEIN, subject .of the Emperor ofGermany, residing at Cologne, Rhine Province, Empire of Germany, haveinvented certain new and useful mprovements in Bottle Caps 'or Closuresfor Bottles, Jars, or other Receptacles, of which the following is aspecification.

. iv invention relates to improvements in bottle caps or closures forbottles, jars, or other receptacles, and more particularly to that classofcaps; or closures comprising a torn and adapted to be rigidly caneasily be torn, still maintains its i, grasped y on the upper part neckof the bottle or receptacle 1 to clamp a cork or jar,

capsule of sheet metal which can easily be connected to an outer orinner shoulder provided on the and thereby or sealing disk to the bottleand which capsule is formed, at its fiat portion, with a tongue-likethumb-piece which can be easily raised out of the fiat portion of thecapsule and grasped by the fingers of an operator, in order to tear thecapsule and thereby to open the bottle or jar.

The-object of the im rovements is to provide a closure of this 0 asswhich, thoughit strength and holding power, whereby a very safe andsecure closure is obtained which is capable of withstanding the highestinternal ressure ordinarily employed on bottled goo s. For this pu ose,the tongue adapted to be the fingers of the operator is not ormed by acontinuous slit, but of several sections between which bridges ofunweakened metal are left, which, however, will easily be torn whenraising the thumb-piece out of the face of the capsule and ulling thesame with the fingers. The bri ges are so distributed over the slit asto provide a -reiable connection between difierent' parts of the rim ofthe capsule and, preferably, they are located at diametrically oppositeparts of the disk, so as to provide an unbroken metallic band extendingalong a diameter rom one side of the capsule to the opposite side.

In the example illustrated in the drawing, have shown a ca sule providedwith a wellknown downward ed to be bent or crimped into a groove formedof a bottle or jar. But I wish it to be understood, that my invention isnot limite to the particular form of the capsule or to the use of saidcapsule in combination with the bottle illustrated.

-as to provide a reliable y extending flange adapt- In the drawing,Figure l, is a cross-see have a shaEpe difierent from that of Figs. 2

and 3, and ig. 5, is a cross-section of a bottle provided with theimproved closure.

Like letters of reference are used to indi cate corresponding parts inall the views.

In the example illustrated, a bottlea is formed near its mouth with acap holder groove b. A capsule c is provided with a depending flange (1adapted to' be smoothly bent or crimped into or under the cap holdergroove 6. Within said capsule, and on the top of the neck ofthe bottle,a cork or sealing disk 6 and a sheet metal cork holder disk 2' arelocated, which, by the pressure exerted by the capsule c, are held inscaling contact with the. face of the bottle.

eferring now particularly to Fig. 2 it will be seen that the capsule cis PIONlClBd, at its flat portion, with a slit of substantially circularshape and locate( tance away 'from the rim of the capsule, so

circle, the connot the form of a continuous 'nection of the thumb-pieceg at one part of its circumference in known manner not being broken, andat this part substantially parallel known slits or scored portions I:are rovided extending from the ends of the s it J towards the rim of thecapsule and providing a tongue piece, whereby, when tearing the cap, therents are directed towards the rim of the latter. Now, in order tostrengthen the capsule, the slit f is interrupted at a further part,soas to produce a secondv bridge Z connecting the thumb-piece g with themargin of the capsule. As shown in the drawing, the said bridge Z islocated diametrically opposite the aforesaid tongue iece, and where butone additional bridge l is provided, this ar-' rangement' is consideredto be the most effective one, because the continuous and strengtheningstrip thus produced extends,

along a diameter, from one side of the rim within a certain disenough togive the said diametrical strip sufiimade which strikes a pair sodisposed as cient strength to withstand the force exerted thereon byinternal pressure of the bottle. But it can easily be broken, whenraising one side of the thumb-piece g. I

In the modification shown in Fig. 3, two bridges Z are provided, whichare so located as to provide a continuous diametrical stripsubstantiallyperpendicular to that of the previous example.

Afurther modification isshown in Fig. 4; In this example, the slits arenot ofcircular shape, but at one side ,of the capsule a thumb-piece g isprovided by" a slit having its ends arran ed at a certain distance fromeach other. exerted on the thumb-piece a rent will be t slits h locatedat a distance from the ends of the slit f and to be'certainly met by therentproduced. The said slits It will direct the rent with certaint tothe circumference of the capsule. It w' 1 be seen, that by thisarrangement a very broad brid e l is produced which, -however,-can'eas'y be torn. The capsule thus. produced has a considerable strength. Inthis construction also, a

continuous diametrical strip is provided, that is, it is possible todraw a diameter on the cap without intersecting any one of the slits.

en t'earing'the cap by a force I claim: 5 1 L'A closure for-bottles,jars, or other receptacles comprising a capsule made of a metal whichcan easily .be torn and. adapted to be secured to the mouth of thereceptacle, said ca sule being formed with slits providing at umb-pieceand leaving a continuous diametrical strip on the cap so that adiamete'r may be drawn on the cap without intersecting any one ofthe-slits.

2. A sealin cap for bottles. and other receptacles, sai ca havinga topformed with slits theinner wa s ofwhich are'curved and partly surround athumb-piece, said slits being so interrupted as to leave a continuousdiametrical strip on the cap. I 3. A sealin cap for bottles and otherreceptacles sai cap having, a top formed with a thumb-piece, a tongueconnecting said thumb-piece with the body of ,the cap, a bridge locatedat a point of the thumb-piece diametricall opposite said tongue, andslits extending a ong the edge of the thumb-piece from the tongue to thebridge.

In testimony whereof I have hereuntoset my hand in presence-of twosubscribing witnesses. i A. I ELISE GOLTSTEIN.
